non tilt balancers

A quick learner from Wilmington NC says:
I need two sets (metal and plastic hardware) for the long windows (29 inches of just metal part), and one set for small window (17 inches long metal part alone). They're 1/2 width.

Thanks for posting. I can't quite tell what balance you have based on these pictures. I think you could have either our Series 390 or Series 351 channel balance, depending on the size of you bottom shoe. See what you think.
